It is to be further understood that wireless device can based on any one in above-mentioned triggering come trigger notice or report, But also triggering reason can be noticed (for example can provide notice on disturbance regime to network, and the notice can be wrapped Information described herein is included, but does not indicate that the disturbance regime is potential interference situation or actual interference situation) (for example may be used Not indicate that the interference is based on reactivity triggering or actively triggering)).It is to be further understood that described herein Solution is equally applicable to be disturbed or potentially interfere with the other technologies of LTE technologies by LTE technologies.Equally, when When wireless device can determine that LTE technologies are wished to be powered or are possible to ask to set up RRC connections, it at this moment can trigger and disappear Cease (notice) and transmit message (notice) to the network of another technology, indicate LTE technologies and presently described LTE technologies quilt Configure the frequency range supported, and it is possible thereby to other frequency ranges supported.So, attacker and aggrieved party RAT are likely to It is controlled by wireless device.Solution described herein both may be used alone, can also be used in combination.
Fig. 3 is referred to back, for example, 310, is contained and is configured to alleviate, reduce or avoid disturbance regime The information of operation can be received and (can for example receive the configuration information for wireless device).Then, can be to the letter in 312 Breath is handled, to alleviate, reduce, prevent or to avoid disturbance regime.For example, in one embodiment, when 308 After providing disturbance regime notice to network, network can help wirelessly to set via one or more solutions or process It is standby to prevent associated expection or potential interference, this will be hereinafter described in more detail.In order to provide this side Help, the network of all networks 412 as shown in Figure 4 etc can be provided to wireless device contain one or more operations, process, The information or solution of rule or agreement, the wireless device then can receive the information or solution 310.Then, The wireless device (such as wireless device 400) and/or one or more components therein (for example Interference Detection and avoid module 410) described information or solution can be handled, to alleviate, avoid or reduce the interference shape in 308 to network-reporting Condition.
More specifically, in one embodiment, for example, when network is in 308 reception notices or ability, the net Network can transmit or perform the one or more of procedure below, and these processes can be received by wireless device 310, and by nothing Line equipment or component or module in it are handled, to alleviate, reduce or avoid the interference produced by disturbance regime.
Wireless device (or WTRU or UE) can be configured to the disturbance regime in report and supervision equipment by network.Example Such as, wireless device can be configured with event C1 or the existing event extended.Once this configuration is carried out, then wireless device It can start to monitor and report that disturbance regime is notified according to above-mentioned triggering.310, wireless device can be received and this event Associated information, and can be handled in 312, so as to perform or configure the event.
Network can also provide the information associated with network capabilities for wireless device, the information include on network whether The instruction of interference mechanism that can be in processing equipment.310, message can be set in RRC connections for this information or other are any Wireless device is provided in RRC information and is received by the wireless device, and is handled in 312.In addition, the information It can also be determined by the presence or absence of the configuration of report event or message.
Network can also provide fallback value or scale value to wireless device, and it can be received 310.Then, nothing Line equipment can handle the rollback or scale value 312, so that wireless device can use the rollback or contracting when producing interference Put value and reaction is confined to the interference, this point can described in more detail hereinafter.
As replacement, network can send new measurement to wireless device and configure message, and wherein the message, which has, is available for nothing Line equipment starts other frequencies of measurement and/or RAT list, and can receive this new measurement configuration in 310 and disappear Breath.Then, can be handled in 312 it is new measure configuration message, to start to measure the frequency included in list and/or RAT.
According to another embodiment, network can perform controlled activation to the RAT components or equipment for producing interference.Example Such as, aggrieved party RAT components or equipment and the RAT components or equipment of generation interference are likely to need to activate or be possible to It is activated.In this situation, network can perform following one or more methods, rule, process and/or rule, and The information with methods described, rule, process and/or rule association can also be provided to wireless device, described information can be 310 Received, and handled 312.
For example, in one embodiment, it can detect from the activation request that RAT equipment coexists or disturb (for example cause to produce disturbance regime 302) during situation, RAT equipment (will produce interference as performed transmission) will not be swashed immediately It is living.The RAT equipment or activation of service coexisted can be delayed by the predefined period, so that for other equipment, (such as aggrieved party RAT is set It is standby) time is given to take appropriate action to avoid interference.According to an illustrated embodiment, network can be in the letter received accordingly Notify this delay (such as 310) to wireless device in breath.Then, then wireless device can postpone to activate RAT equipment (examples Such as 312).According to an embodiment, if connection requirement in Coexistance device depend on technology (for example its whether be WiFi, bluetooth, LTE, GPS etc.), then the value of delay timer can depend on technology or ask the application of activation equipment Or service.It is to be further understood that delay timer described herein can not be carried out or configure.In this case, if It is standby to be activated in the case of not any delay.
According to another embodiment, network can also be sent to wireless device allows the RAT equipment of ISM equipment etc to open Dynamic notice, the notice then can be received and handled (such as in 310 and 312) by wireless device.The notice can be incidentally (piggyback) is transmitted to MAC control elements (CE) order in existing RRC information or new RRC information.As replacement, lift For example, when no replacement solution or when not having pending data to send in node B cache, network can be to wireless Equipment sends the notice that refusal ISM equipment starts, and the notice can be received and handled (such as 310 by wireless device With 312).According to an illustrated embodiment, this other RAT equipment that might also depend on such as LTE equipment etc is transmitted Data priority.
As replacement, network can send ISM activationary times to wireless device and notify, and wireless device can receive and Handle the notice (such as in 310 and 312).Based on the estimation to remaining data to be sent and channel condition in buffer, institute State ISM activationary times and notify it can is multiple frames, subframe or multiple values by millisecond or in units of the second.The activationary time can be with It is coupled with reconfiguring message, wherein the message that reconfigures can be any solution (switching, one listed above Individual or multiple carrier waves are deactivated, and RAT is redirected).The notice can incidentally be sent to existing RRC information or new RRC information In MAC CE orders.Only after the activationary time noticed with signal is terminated, wireless device can just activate ISM equipment.
For these solutions, such as method described herein, rule, the triggering of process and/or agreement and event For configuration, they might also depend on the priority of radio access technologies (for example, LTE priority can be higher than GPS, vice versa).In addition, the service type that technology is provided can also be used as additional standard.More specifically, for example, such as Fruit just with certain technology perform urgent call, then compared with it is beneficial that indicate symbiont techn in some period without transmission, Wherein described instruction can be received 310 and handled 312.Wireless device can not also trigger report described herein Processing.For example, the information of the component of symbiont techn is not transmitted or activated in some period or instruct it when being received 310 Afterwards, the instruction or information can be handled 312, so that wireless device can stop the group associated with symbiont techn The activation of part, hereinafter this will be described in more detail.
If in addition, transmitted high-priority service, such as, but not limited to urgent call, earthquake and tsunami early warning system System (ETWS) or any kind of emergent alarm message, then more it is beneficial that another technology is without transmission.One In individual embodiment, this can be performed automatically in a wireless device.For example, when this business can be detected, wireless device It can indicate that ISM stops transmission.As replacement, (such as 312) can also be handled and use is sent to wireless device from network The explicit message or information of (for example being received 310).More specifically, the message can indicate that wireless device stops ISM transmission, And LTE technologies can indicate that other technologies stop.When occurring higher priority service, same situation is to another technology Speech is also applicable.LTE technologies can transfer the status report to network, be noticed so that network is known in report with signal The predefined period in do not dispatch wireless device.
For example, in one embodiment, based on receiving (such as 310) from network and by wireless device processes The information of (such as 312), wireless device can be by the activation (or transmission/scheduling) of the RAT components of ISM equipment etc or equipment The delay predefined period.Once what kind of operation no matter expiration of time limit, occur or act at LTE ends, can start ISM equipment (or being scheduled to perform transmission/reception to it).Activate the clothes that delay timer can depend on asking in ISM equipment ends Business or ISM device types.Similar concept or process is also applied for LTE, if wherein being carrying out certain ISM activities or mistake Journey, then LTE ends can be activated (such as even by the data transfer of network scheduling) in delay in the period is defined.Once by being somebody's turn to do Time, then WTRU can recover normal LTE operation.
As replacement, the LTE equipment included in wireless device can be remained turned-off with implicit commands ISM.If LTE equipment shows ISM equipment is ordered to remain turned-off likes, then wireless device can cancel delay Active Timer, and be returned in the predefined period Move back and (will not for example, at least be retried in Backoff time).Once backoff timer is terminated, then wireless device can trigger another and refer to Show or notify, and operation that is thus receiving or being included in can be performed as described above.It is right according to an embodiment For some LTE application types of urgent call or high-priority message etc, it is likely to require and enforced and does not open With the operation of another technology, wherein the high-priority message can be such as but not limited to ETWS.
In addition, if there is switching command or redirection at LTE ends, then can be activated before delay timer termination ISM equipment.Or, if TDM mode described herein can be supplied into wireless device, then the equipment can enter activity Pattern, and perform according to the pattern provided transmission/reception process.Once successfully completed one of aforesaid operations or its Combination, then wireless device can start ISM equipment, or if receiving the refusal order for carrying out automatic network, then wireless device can To interrupt the request.
According to another embodiment, wireless device will not receive (such as 310) and carry out automatic network and be possible to include Order for its notice or the information (such as 308) appropriately operated, and with supporting one of radio access technologies Or the associated timer of multiple components can be terminated, such as ISM device activations delay timer.In this embodiment, nothing Line equipment can perform following one or more operations, and (when RLF is possible to prevent to be connected with network, these are operated can be with Performed 306):Refuse ISM device activations and notify user;After last time response, wait the delay of ISM device activations fixed When device terminate, and if there is no data to be transmitted in wireless device buffer, then allow ISM device activations;And/or wireless ISM is allowed to activate (similar to DRX circulations) in the limited period of time for the definition that equipment is implemented or network is noticed with signal.
Once interference mitigation operation failure, then wireless device can refuse activation support radio access technologies component or Equipment, such as ISM equipment.The activation is possible to be rejected in the period of some definition, and the period can be believed by network Number notice or by wireless device its implementation defined in.As replacement, wireless device can restart associated with this class component Notification procedure, such as ISM equipment notification procedure (for example can be in 312 processed processes).Number of retries is possible to limited In by network notifications or depending on the value of wireless device (such as in its implementation), born with avoiding increasing the signaling in network Carry.This situation as described above is possible to alternatively cause switching between triggering technique.For example, in an embodiment In, the situation may cause wireless device to be switched to ISM technologies (such as WiFi) from LTE.The situation is it is also possible to depending on just Request starts ISM data or the priority of application.
In another embodiment, by ensure produce interference technology between have enough frequency intervals by Interference reduction coexists to admissible grade (such as by RAT frequency division multiplexing) so as to allow to produce the RAT disturbed. In such cases, once receiving the notice or report, then network can perform one of following operation or its combination, and The information being associated can be supplied to wireless device.Described information can be received 310 and handled 312.
For example, coexisted to allow to produce the RAT disturbed by enough frequency intervals, can perform and be switched to Another frequency or RAT, and wireless device can receive and in 312 instructions of the processing to this switching 310.
As replacement, wireless device can use other frequencies and/or RAT (notice provided according to wireless device, the frequency Rate and/or RAT be considered as to have no problem or problem is less) measuring control information configure, the information can for example exist 310 are received and are processed 312.This can allow wireless device to measure other frequencies in advance to be avoided radio bearer setup complete (RLF), or wireless device can also be allowed reversely to be reported to network, and supported another is gone to before frequency degradation The switching of one frequency, so that another technology does not suffer from interference, or this interference of rapid recovery.
If in addition, RLF occurs in a wireless device, then wireless device, which can determine to disturb in equipment, to be continued, And RRC can be performed in another frequency do not disturbed by symbiont techn to rebuild (namely instead of having in current service The reconstruction for cell is performed in the frequency of problem).As replacement, wireless device can transform to idle pulley immediately (for example Do not attempt to rebuild), and process is set up in initiation RRC connections in interference-free new frequency.In this case, cell is selected It can be changed with reuse adoption process, so that avoiding those the frequency range disturbed in equipment occurs.
As replacement, network can send to immediately measurement or result request (for example with UEinformationRequest (UE information requests) RRC information), and wireless device can receive before the handover is performed (such as 310) and (such as the 312) request is handled, returned with avoiding occurring on previous cells switch failure and WTRU Move back.
, can be to be easily disturbed in what is reported in addition, in order to realize the compossibility with enough frequency intervals Region in frequency (for instance in frequency in troublesome frequencies list) perform (for example, 312) remove active carriers (for example Disable assisted cell simultaneously or remove configuration) reconfigure (such as 310 receive), or can be carried in main carrier and auxiliary Switching (frequency having no problem for example is switched to from troublesome frequencies) between frequency is performed between ripple.Described reconfigure can be by nothing Line equipment is received (such as 310), and wireless device can be filtered using supplement RF in remaining working frequency and (for example existed 312)。
If Pcell is in the region (and Scell is not at) that is easily disturbed, then can perform Pcell with it is configured Scell quick change, and can provide on the information quickly changed or instruction, thus, lift to wireless device For example, wireless device can process the information to the change of execution fast cell in 310 receive informations or instruction and 312.
It can equally be performed for another frequency (such as switching) or RAT redirection.The processing can be used RRC connections are refused or release message is performed, and the message can be received and handled (such as in 310 and 312) by wireless device. Cell Change Order (for example receiving 310) can be additionally sent to wireless device to perform frequency or RAT changes (for example to exist 312 processing).
According to an embodiment, once successfully completing switching, then the component of radio access technologies can supported to live Dynamic (such as ISM device activities) period allows the different list of frequency of wireless device holding and RAT priority to avoid the occurrence of Ping-pong, or remove from candidate list troublesome frequencies.As replacement, as described above, wireless device can be by problem Frequency reports that thus network will not provide instruction or configuration wireless device is measured on these frequencies to network.Another In one embodiment, the list can be by network in system information elements or RRC measurements configuration message and applied to these Noticed in the rule of particular condition with signal.
In another embodiment, in the presence of by ensuring between transmission and/or reception in RAT equipment or component Between coordinate, and thus limit the interference (being for example time-multiplexed by RAT) that is produced to another RAT equipment of a RAT equipment, It can make it that producing the RAT disturbed coexists.In this case, once detecting the disturbance regime in equipment, or receive Notify or report, then UE or network can perform one of the following or its combination, it is possible thereby to by the information being associated Wireless device is supplied to, and described information can be received 310 and handled 312.
For example, the TDM that can be configured between this RAT (as described herein) allowed in a wireless device is operated not It is continuous to receive (DRX) cycle or gap/pattern, hereafter just this is described in more detail.It can additionally match somebody with somebody for wireless device The semipermanent scheduling of the TDM operations or FDD either-way operations that account in wireless device is put, so as to logical in wireless device Know/Ability Signals or this operation of Informational support that is contained therein in the case of allow TDM equipment operation secret sharings.Its In for example, the wireless device can 310 receive the configuration, and 312 handle the configuration.
In another method, it can perform same in two or more RAT components or the equipment in same wireless device (such as adapting operation, former to minimize or eliminate the transmission on each RAT on one or more RAT components by Shi Tongxin Barrier), to ensure time coordination property, and thus, it is possible to make RAT components or coexistence.In this case, when in mobile terminal Or when can detect and/or report the RAT for producing interference in network, keeping moving by adjusting the opportunity transmitted and received Allow to produce the RAT work disturbed while terminal has been connected.
For example, in LTE system, when wireless device or eNB can be in recognition device disturbance regime when, Ke Yiying Coordinate the mould in discontinuous transmission (DTX)/DRX, LTE scheduling/unscheduled gap or equipment between wireless device and eNB The process of formula, to allow the communication on the RAT replaced, while the influence to LTE connections will be minimized or eliminated.In an implementation In mode, up-link (UL) and downlink (DL) transmission can be now uniquely determined, and thus, enable and disable DL and/or DL Transmission can be independent.
, can if will recognize the interference for replacing RAT in a kind of method for coming to coexist by time coordination To coordinate the periodicity DTX/DRX circulations of the temporal mode in equipment between wireless device and eNB, and in 310 by week Phase property DTX/DRX circulations are supplied to wireless device and it are handled in 312.The particular cycle configured and transmission/ Receiving length can be with the specific transmission/reception demand unique association for replacing RAT.For example, wireless device can be touched to network Send out the report on asking the gap for being used to replace RAT.The request (for example being received 310) can be including but not limited to following One of information or its combination:The type of skill;Another technology will reception/transmission service type;And/or another RAT Can properly be worked required required pattern (such as length and cycle), and the pattern can be used to be permitted for such as LTE Perhaps the form of the index of DRX mode or for the different predefined pattern set that use situation or service coexists Form, can also be more specific form.
According to an illustrated embodiment, in the case of 802.x WLAN, once perform access point search And association, then LTE system can enable mould in the DTX/DRX or equipment of the special design for the operation that account on 802.x RAT Formula, and when discharging access point association, LTE system can disable the enhanced DTX/DRX of pattern in DTX/DRX operations, equipment Operation or TDM schemes.LTE transmission gap is designed to ensure periodically to transmit with successful 802.x MAC levels, to protect Hold the IP agreement of higher.For example, in order to help network to discharge gap, wireless device can also be to another technology of network-reporting It is disabled/to deactivate or do not continue to produce interference.
More specifically, in an illustrated embodiment, wireless device can use transmission time in 802.x storehouses Algorithm for estimating.More precisely, based on 802.x IP storehouses, cache size and 802.xx radio conditions, wireless device can How many transmission cycle are needed to empty 802.x related caches to assess.For example, this can be expressed into be LTE subframes or frame times Number.Wireless device can send event or MAC CE comprising estimated 802.x activity needs.If in addition, 802.x is related Service needs cyclical transmission, then can notify to mark using the specific seeervice cycle for eNB.
In another embodiment, when the service in support is changed or determined to transmit or receives demand, wirelessly Equipment can be changed with request mode or request mode.Radio bearer set up or from higher level for special services Set up or the instruction of release can be used for setting of the triggering for some TDM modes.These patterns are also based on to be sent UL data volumes or it is dynamically adjusted for the estimation of DL data to be received.
Once receiving notice or asking (such as 308), then network can correspondingly permit DTX to circulate or pattern, its Described in circulation or pattern meet asked service transmission, and can be the activationary time in units of frame and/or subframe, And/or the duration in units of licensed DTX loop numbers, the circulation or pattern can be received and (for example existed 310) it is and processed (such as 312).Further it is provided that the information to wireless device can include the number circulated with the DRX of license Measure the duration for unit.The information can reconfigure message by MAC CE orders, RRC, new RRC information or thing Reason layer indicates to provide.
As replacement, wireless device can use auxiliary DRX configurations, and the configuration can be by network by for being equipped with The dedicated signaling for producing the WTRU of the technology of interference is broadcasted or provided, and can be received and (for example to be existed by wireless device 310) it is activated with processing (such as 312), and based on the order from eNB.
If in addition, eNB cachings are with the data for WTRU, then network can refuse wireless device DRX requests.One Denier RAT activity ends, then wireless device can use the above method to notify eNB, and recover normal operation.As replacement, Network can be sent to wireless device to be removed the RRC of the DRX configurations replaced and reconfigure message or MAC CE orders (it can be 310 are received and are processed 312).
It can also be pre-configured with and using DRX/DTX or LTE scheduling/unscheduled pattern, so that use time coordination comes true Protect compossibility.For example, when detecting the trigger criteria of AD HOC, the pattern being pre-configured with can be selected.Each pattern It can be learned by the configuration index of particular configuration.Then, selected configuration index can wireless device and eNB it Between noticed with signal, so as to the synchronous pattern.
According to that where can detect trigger criteria, wireless device or eNB can determine the new DRX/DRX asked Which physical signal is pattern can include.In order to implement appropriate scheduler operation, it is possible to need a kind of certainty signaling side Method coordinates DRX/DTX between wireless device and eNB or LTE scheduling/unscheduled pattern.For example, MAC CE signalings can be used In the specific pre-configured DRX/DTX mode index of identification.
In addition, when the pattern that detects changes or needs change pattern, wireless device can be changed with spontaneous execution pattern, And send on changing the instruction with the time.As replacement, wireless device can there occurs this change (example to network advertisement Pattern as required changes), recommend a kind of pattern or indicate to there occurs which type of changes, and wait carrys out automatic network Implicit commands to perform this change, wherein the order can 310 receive and handled 312.This dynamic is led to Knowing can be carried out by MAC CE, and to recognize the change or pattern, network can be believed by another MAC CE, by L1 Order comes with signals reverse notice or the new pattern of response by RRC information transmission.
In the method that RAT coexists is realized in another permission by time coordination, quick MAC or PHY signalings can be with For creating the dynamic transmission/reception gap asked, to take the transmission on the RAT of replacement into account.In the method, when When transmission/reception demand is detected on the RAT of replacement, LTE connections can quickly initiate a kind of pattern in the known period, so as to Take the communication on the RAT of replacement into account.In a solution, the pattern can be pre-configured with by RRC.Such case can be The result that symbiont techn is present is reported, or activates the result of the technology.Once being preconfigured, then the pattern can root According to the pattern and demand of replacing RAT and using MAC or PHY by quick activation/deactivation.
It can also be used for realizing that RAT coexists without buffer status report (i.e. sky BSR).In this case, once receiving this Plant and notify or report (such as 308), then network can perform one of the following or its combination, and will can close therewith The information of connection is supplied to wireless device, and wherein described information can be received 310 and handled 312.
For example, wireless device can by network send be referred to as not the new type of dispatch request (NSR) request come to It is scheduled in order to avoid the RAT of interference co-existence that network indicates that (such as by the notice 308) it is not intended to.The NSR may be embodied in In MAC packet data unit (PDU), or as an existing MAC CE part, or the new MAC CE that can be defined.
NSR can include one or more of following information.NSR can include:Indicate whether avoid uplink Road or downlink scheduling or the detailed catalogue value (enumeration) that should avoid both simultaneously, instruction scheduling is avoided should Start the Boolean (Boolean) being also off;The period of scheduling can be avoided, it estimates and possible generation with wireless device The period that RAT interference coexists in other is corresponding;It can proceed by and dispatch the start frame avoided and subframe (as replacement, institute State scheduling to avoid to immediately begin to carry out when network receives NSR);The end frame and subframe avoided can be stopped dispatching (as replacement, the scheduling, which avoids that another can be received in network, to be shown to tie when can stopping dispatching the NSR avoided Beam);And/or it is available for the index of the predefined pattern list of wireless device selection.
Then, wireless device can follow one of following rule related or based on NSR use to NSR triggerings Or its combination.If wireless device have sent sky BSR to show that wireless device is buffered in identical TTI or last X to network It is sky inside individual TTI, then wireless device need not send NSR to network in this TTI and be avoided to ask UL to dispatch.As for Change or supplement, wireless device can periodically send NSR.Can be with the NSR timers of delimiting period, the value of the timer Both can be it is fixed, can also be by network configuration.
NSR can also be used in combination with empty BSR report processing.More specifically, wireless device can still report reality Buffer status, but supplement is used as, it can also include one of above-mentioned NSR information or its combination, to indicate it according in advance Definition or configured pattern and be partial to without transmit or start without transmission.Network can then match somebody with somebody by RRC Put or MAC configures (such as new MAC CE) to enable or disable the NSR in WTRU.
Wireless device be also based on caching estimation size and the radio condition (modulation and code rate) for replacing RAT and Fast signalling message is sent on a physical layer, or sends the MAC CE (examples in the RAT transmission request LTE eNB gaps to replace Such as 308).These gaps can be in units of frame or the multiple of subframe.Then, can to send allowed transport gap long by eNB Spend and the possible start offset in units of frame or subframe, and these information can be received 310 and obtained everywhere 312 Reason.
As replacement, eNB will not permit any gap, and it is possible to send refusal to wireless device and notify.One receives To service-denial, in order to avoid increase network signalling load, wireless device can perform backoff timer (example for the RAT replaced Such as 312).Once the backoff timer is terminated, then wireless device can send replacement RAT service requests again.In addition, limited Number of retries can both be noticed by network with signal, or defined by the implementation of wireless device.
According to an illustrated embodiment, it be can not be for initiating the standard of transmission gap on each 802.x The transmission of MAC layer.The processing for enabling transmission/reception might also depend on TCP or the FTP transmission of higher.To/from replacement The processing of RAT switchings can take the influence to higher agreement into account.For example, transmission can intentionally be fallen on a RAT so as to Transmission rate is reduced, or takes those lower-priority datas for service delivering not necessarily into account.
In addition, all requests described herein can be by forbidding timer to be limited, in order to avoid wireless device frequently please Ask.More specifically, if can be according to any embodiment described herein come trigger request or instruction, wireless device can To initiate to forbid timer (such as 312).In the event of changing, another instruction is probably triggering and forbids timer just In operation, then wireless device can not transmitting request, and the timer ends can be waited.Once timer ends, such as Fruit trigger condition is still set up, then wireless device can send pending request.As replacement, if forbidding what timer was run While trigger request, then wireless device can cancel the request.
In another embodiment, network can allow the RAT for producing interference to be total to by the DRX for TDM schemes Deposit.In this case, once receiving this notice or report, then network can perform one of the following or its group Close, and the information being associated can be supplied to wireless device, wherein described information can be received 310 and obtained 312 To processing.
For example, a kind of possibility solution for being used to solve compossibility (such as ICO) problem in equipment can be taken (TDM) scheme of time division multiplexing, it includes ensuring that radio signal transmission will not coincide with the reception of another radio signal. In LTE, TDM mode is in the scheduling with network configuration or wireless device suggestion and converted in the case of the unscheduled period 's.
A kind of method for realizing TDM is by means of using DRX.According to an embodiment, it can be envisaged that another technology It is possible to be transmitted in the LTE inactive times (unscheduled period), and then will not in the LTE activity time (scheduling slot) It is transmitted.
As shown in figure 5, the DRX mode for LTE can must monitor physical downlink control channel with WTRU (PDCCH) run duration (On duration) period defines, or can use the DRX for allowing WTRU to enter dormancy The period on opportunity defines.
For DRX, a critically important concept is the activity time, and it is the duration period of minimum length, and And can be according to network scheduling and wireless device triggering by infinite expanding.In the activity time, wireless device must be monitored PDCCH, and transmission can be performed or received.Therefore, because different events may make wireless device rest on the activity time, Even making WTRU, never the activity time wakes up and transformed to the activity time, there is a problem in that wireless device can not be in DRX occasion Period in remain inactive for (i.e. dormancy).Some examples are new DL transmission, UL licenses, pending dispatch request, Stochastic accessing Contention solution and mixed automatic repeat request (HARQ) are retransmitted.In the extreme case of infinite expanding activity time, nothing Line equipment has no chance to enter dormancy, and can not in TDM schemes with ISM technology co-existences.In addition, no matter whether WTRU monitors PDCCH, WTRU can be received and transmission HARQ feedback when expecting.Even if this means wireless device is not in the activity time In, answering/no answering (ACK/NACK) and physically row chain are still received on physics HARQ indicator channel in the presence of it ACK/NACK risk is transmitted in road control channel (PUCCH).
One or more solutions described herein can be used for DRX.For example in one embodiment, by using DRX schemes, can allow to implement coordination coexists across different RA.But in order that using DRX schemes, it is necessary to which modification includes crowd Many amendment, enhancing and limitations.
For example, for coexisting between different RAT, the scheduling time hereafter quoted, which can correspond to network, allows LTE quilts The time (such as transmission/reception) of scheduling, LTE unscheduled (or ISM is unscheduled) then can correspond to be the distribution of ISM equipment Time is transmitted the time of (when there is problem in DL) or reception (when LTE is interfered in UL).
It is described that the inactive time that can be designed to make DRX to circulate coexists is relative with the LTE ensured the unscheduled periods Should, and DRX activity time is corresponding with LTE scheduling slots.So it is likely to require and is carried out more between different technologies It is dynamic to coordinate.As replacement, described coexist can be designed to make LTE scheduling slots corresponding with run duration.Make To replace, according to either method described herein, when can configure or determine in a wireless device specific scheduling/unscheduled Section/subframe.
This method, which is had an advantage that, can more efficiently use the LTE unscheduled periods.If other RAT are known a priori by LTE The unscheduled period, then idle period is not present between detecting LTE inactivities and being transmitted on another RAT is initiated.This Outside, other RAT can be transmitted to the known end of LTE unscheduled periods, without making ongoing Transmission always.This For being even more important for being switched fast between unscheduled period very short RAT.
What embodiment described herein was discussed is the method that TDM operations are realized using any such scheme.In addition, right In DRX activity times and/or run duration and scheduling/incoherent situation of unscheduled period in WTRU, in DRX operations And WTRU behavior is described while configuring associated pattern.
Dispatch request be can also be used for allowing RAT to coexist, and it is described herein.To UL LTE->ISM DL For interference, the problem pertains only to UL transmission-delay transmission.However, for UL ISM-LTE DL interference, if sent PDCCH, then WTRU can send dispatch request when PDCCH reception suffers damage.
Inactivity timer be can also be used for allowing RAT to coexist, and it is described herein.For example, one In individual embodiment, if wireless device receives new UL or DL transmission, then drx inactivity timers can be started. In the duration of inactivity timer, wireless device may remain in activity pattern, wirelessly be set in the activity pattern Standby continuous monitoring PDCCH.If network dispatches wireless device in the time, then wireless device can be continually maintained in activity Time.
For being configured to the wireless device according to TDM scheme works, lived in order to avoid being in continuous time Dynamic time, the wireless device can perform one of following or its combination (such as 312).
When new DL or UL transmission can be received, drx inactivity timers are not started.As replacement, this can be with Realized by being configured to zero new value for the introducing of drx inactivities timer.This means wireless device and network can be with According to other triggerings outside drx inactivities scheduling is performed in wireless device operations duration or other activity times.
In another embodiment, it can start in the predefined period and restart drx inactivity timers, And/or started and restart n times.
Can additionally start/restart drx inactivity timers, as long as and activity time for currently passing through be not more than LTE dispatch timers (or defined maximum activity time), then wireless device may remain in activity pattern.Currently pass through Activity time can transform to the activity time first TTI of (such as at the beginning of run duration) relative to wireless device To calculate.
As replacement, it can also start/restart drx inactivity timers, as long as and activity time for currently passing through No more than (LTE dispatch timer-drx inactivities) (or defined maximum activity when m- drx inactivities), then without Line equipment may remain in activity pattern.
As replacement, if the time of execution new DL or UL transmission is corresponding or overlapping with LTE scheduled transmissions, then can To start/restart drx inactivity timers.
As replacement, the drx inactivities timer can be activated, and be appointed but if having in the wireless device activity time What subframe is corresponding with unscheduled subframe (being determined by the pattern configured), then wireless device can be in these subframes Any UL transmission is not performed.Wireless device during these subframes it is also possible to stop monitoring PDCCH.In another solution In, wireless device can monitor PDCCH according to normal DRX processes, but will be by network without quilt in these times Scheduling.In the third solution, wireless device can monitor PDCCH, and be performed if be scheduled in unscheduled subframe UL is transmitted, then wireless device can not perform UL transmission.
Fig. 6 describes the illustration that DL is retransmitted and DL feeds back.If passed as shown in fig. 6, DL occurs in LTE scheduling slots It is defeated, then wireless device can start or restart DRX inactivity timers, still, if DRX inactivity timers are in nothing Line equipment is currently running when entering LTE unscheduled periods, then can stop the DRX inactivities timer, if in LTE DL transmission is carried out in the unscheduled period, then wireless device will not start DRX inactivity timers.
When HARQ two-way times (RTT) timer ends and when starting DRX retransmission timers, wireless device can be with Transform to activity pattern.In order to limit the activity time in wireless device and thus reduce the probability of error, it can perform following One of items or its combination are (such as 312).
In one embodiment, retransmission timer can be not activated by or use.In such embodiment, retransmit It can be sent (such as in run duration), or can be sent out in next inactivity period in ongoing inactivity period Send.Some delays of data transfer are so likely to result in, and the QoS demand of some services may be unsatisfactory for.As for Change, in order to avoid retransmission delay, when WTRU works in this mode, network can use Transmission Time Interval for DL transmission (TTI) bind.
According to another embodiment, retransmission timer can be enabled, and only activity pattern is dispatched with the LTE allowed Period or maximum LTE periods correspondence or overlapping, wireless device can just monitor PDCCH.More specifically, in a solution In, if LTE scheduling slots are terminated when DRX retransmission timers are just run, wireless device can stop timer, and not PDCCH is monitored again.
As replacement, in second solution, WTRU still can monitor PDCCH according to the DRX periods, however, Once ISM scheduling slots/subframe starts, then another technology can initiate UL transmission.Network based on the LTE unscheduled periods can To determine that delay is retransmitted, or weight is dispatched in the case of the excessive risk that can not be alternatively correctly decoded in wireless device Pass.If it is known that interference can be a problem in the period, then eNB can improve the transmission reliability of re-transmission.
In addition, if ACK/NACK repetitions can be configured, wireless device can reduce repetition binding size automatically, also It is that wireless device can reduce this automatically and wirelessly set in the case of needing to avoid PUCCH transmission and its unscheduled period equitant It is standby to repeat to feed back the quantity of targeted continuous ACK/NACK time slots.More precisely, wireless device can be in scheduling Section in using higher configure ACK/NACK repeat, if however, ACK/NACK repeat may with scheduling slot last Individual subframe is overlapping, and it is possible to can be beyond this limitation, then wireless device can be allowed to reduce ACK/NACK numbers of repetition, To be adapted to scheduled period interval.As replacement, beyond the scheduled period, wireless device can be on PUCCH only Repeated using single ACK/NACK, and within scheduling slot using ACK/NACK.As replacement, wireless device can be under One scheduling slot delayed ACK/NACK, and the repetition still configured using higher.Kept away when WTRU enters to disturb in equipment When exempting from pattern, both different ACK/NACK repeated work patterns with signal can be advertised to wireless device by network.
It can also retransmit to enable RAT to coexist using UL described herein feedbacks (ACK/NACK) and UL.
Come ACK/NACK (such as 310), the processing ACK/NACK (such as 312) and again of automatic network in WTRU receptions When passing WTRU data, in order to avoid interference, one of following method or its combination can be used.
When wireless device LTE knows that it has the time in the son in same LTE scheduling slots or the LTE scheduling slots in future Received at frame n+4 when feedback is permitted with UL (for adaptive HARQ), the wireless device LTE can be only in subframe n hairs Send data.The processing can specify that as follows:For subframe n, if wireless device in subframe n+4 everywhere in LTE scheduling slots, So wireless device can send data.For example, if LTE scheduling slots it is corresponding be the run duration period, that Wireless device must check that run duration timer is run at subframe n+4 before UL data are sent.
According to an illustrated embodiment, 4 subframes of the ISM after last LTE scheduling slot without transmission, To ensure that ACK/NACK can be properly received.
For NACK, if it is necessary, wireless device can be by retransmission delay to next LTE scheduling slots.Wirelessly set Standby to indicate HARQ processing ID to network on PUCCH in identical subframe that its transmission is retransmitted, thus network can be by Retransmit associated with specific HARQ processes.
As replacement, if re-transmission can not be performed within activity time or LTE scheduling slots, wireless device can be clear Except (flush) HARQ processes.
As replacement, wireless device can keep the data in HARQ processes, if re-transmission time occurs outside window, Data will not be then transmitted, and when wireless device can not be transmitted every time (such as the subframe corresponding with unscheduled subframe), The wireless device can still continue incremental HARQ retransmission counters, and any other can all change in each retransmit Physical layer parameter.If reaching maximum retransmission in the inactive time, WTRU can remove HARQ buffers, and lose Abandon data.
In addition, if up-link transmission configuration TTI binding, then, if some subframes from the binding are Occur outside LTE scheduling slots, then WTRU can reduce TTI_BUNDLE_SIZE (TTI binding size) automatically.
Additionally using dispatch request described herein (SR) RAT can be enable to coexist, and this is carried out in the figure 7 Display.For example, when that can trigger SR, the SR can be passed in the PUCCH resource of first available appointment Send.Once being transmitted, then wireless device can move to the activity time, and continue to monitor PDCCH, until it receives license (such as 310).Permit if wireless device is not received by UL before next SR opportunitys of wireless device, and if Sr forbids timer not run, then wireless device can send new SR.
In order to provide receiving time to symbiont techn, wherein UL transmits the reception without interference with other technologies, can basis One or more of following rules is transmitted to perform SR.
For example, if SR can trigger and during the first PUCCH resource is the inactive period in a wireless device (such as in run duration or in the inactivity period according to inactivity timer) occurred, then can not transmit SR.Wireless device can send SR in ensuing opportunity, available wherein in the opportunity and the activity time of wireless device PUCCH resource is corresponding.
If there is no available PUCCH resource in activity or LTE scheduling times, then wireless device can be initiated at random (RA) process of access, not have available effective PUCCH resource to network signals.
As replacement, if SR can be triggered and the first PUCCH resource occurs in the LTE unscheduled periods, that SR can not be transmitted.The wireless device can send SR, the wherein opportunity and LTE scheduling slots in ensuing opportunity In available PUCCH resource it is corresponding.
If PUCCH resource is corresponding with any one in WTRU activity times or LTE scheduling slots, then wirelessly set It is standby to send SR.
As replacement, it is consistent that eNB, which may insure that PUCCH resource was assigned with WTRU activity times or LTE scheduling times,.
In addition, in another embodiment, eNB can use the semipermanent scheduling (SPS) for UL to configure WTRU.The SPS cycles can correspond to the activity time or LTE scheduling times of wireless device.
Once SR can be transmitted according to above-mentioned rule or according to regular, then when wireless device must transform to activity Between (such as 312), and continue monitoring PDCCH come receive UL license.However, in order to ensure wireless device is properly received PDCCH and ISM interference will not damage reception, can perform one of following or its combination.
Once SR can be transmitted, then wireless device can continue to remain inactive for (if it is inactive), until WTRU is in the activity time or LTE scheduling slots start.ENB also recalls that in LTE scheduling and/or run duration be living Before dynamic, coexistance model will not monitor PDCCH after transmission SR in WTRU equipment.Fig. 8 shows the one of this behavior Individual example.
As replacement, wireless device can move to activity pattern (such as 312), and ISM equipment can continue UL transmission, but ENB can be ensured by dispatching or being dispatched in the run duration period wireless device (such as transmitting PDCCH) in LTE will not Clash.Once sr forbids timer ends, then identical rule is also applicable for pending SR.
If wireless device does not initiate SR or RACH according to process described herein, then can configure in a wireless device Or pre-define some rule, wherein the rule refer to wireless device can be in inactive period or unscheduled subframe It is middle to wake up what type of data transfer to transmit SR or RACH preambles (peramble).More specifically, network can be by WTRU is configured to revive to send data only for one of the following or its combination:Specific priority of logical channels; Priority of logical channels list;Minimum priority of logical channels, that is to say, that if the priority of logic channel is higher than the minimum Value, wherein having data to transmission for the priority wireless device, then allows to wake up WTRU;Specific logic channel group;Patrol Collect channel logo;Logic Channel Identifier list;And the NAS service requests for specific access grade.In the later case, If access grade belongs to high priority access grade, such as urgent call, then no matter there is what kind of ICO rule, wirelessly set It is standby to revive and trigger SR.The business of these types has restrained the possibility for producing the interference to another technology.In addition, If ISM transmission potentially interferes with DL LTE receptions, then the ISM transmission can be stopped.
Additionally using random access procedure described herein RAT can be enable to coexist.For example, if can be with Trigger random access procedure, then the Stochastic accessing money that wireless device can be allowed in the prachConfiglndex configured Preamble is transmitted in source frame and subframe.Once preamble can be transmitted, then wireless device is needed to be in the activity time and be directed to down Row situation monitors PDCCH:1) accidental access response window (window starts from 3 subframes sent after RA preambles), or Person is until wireless device receives the DL with RA radio network temporary identifiers (RNTI) and assigned;And 2) in the decision of contention solution When device transmit to receive UL licenses after Msg3 or receive contention while run and solve message.
If UL transmission is interfered to another technology, and if physics RACH (PRACH) resources that are configured or Msg3 permitted hours correspond to wireless device the inactive or LTE unscheduled times, then can perform it is following in one or It is multiple.
Preamble can be merely deferred until it is next can be equitant with wireless device activity time or LTE scheduling slots PRACH resources.ENB may insure that the Msg3 licenses are provided according to LTE scheduling or inactivity period.
In addition, being once in preamble or msg3 transmission opportunity, then wireless device can be notified to another technology The transmission that will be carried out, and no matter whether the transmission is overlapping with activity or scheduling slot, and wireless device can transmit data.
For RAR and Msg4 down-link reception, wireless device can perform one or more of following (example Such as 312).If random access window falls into activity or the scheduling slot of wireless device, then wireless device can be monitored PDCCH.In RAR windows or scheduling (activity) at the end of the period (or if can receive RAR), wireless device can stop Monitor PDCCH.
In addition, the only contention solution time falls into WTRU activity or scheduling slot, wireless device can just be monitored PDCCH.Timer or scheduling (activity) at the end of the period (or if msg4 can be received) are solved in contention, and WTRU can be with Stop monitoring PDCCH.
If RAR windows fall into the inactive or unscheduled time, then can change RAR windows, so as to when earliest Machine starts, wherein on the opportunity, RAR windows start according to RA process rules and scheduling/activity time.To make eNB Know that wireless device can perform reception in scheduling slot and RAR windows can be moved, source eNB must be carried in preparation switching For information in equipment and pattern.Special preamble is assigned with if WTRU, and eNB knows that the WTRU is in equipment and disturbed Mode of operation, then the solution will normal work.
It can also operate to enable RAT to coexist using tool guaranteed inactive time described herein DRX.Lift individual Example, it is a kind of to be used to realize with the activity time not ensured in addition to being configured with the DRX of run duration and circulation DRX method can also have maximum scheduling and unscheduled period configuration.In an illustrated embodiment, scheduling or unscheduled The duration of time can be more than the run duration period, wherein in the run duration period, wireless device is still It can so be allowed to perform common DRX processes, that is, be supervised discontinuously and continuously according to different DRX timers and triggering Depending on PDCCH.As shown in figs9-12, scheduling and duration of unscheduled period can change, and can depend on situation and Symbiont techn demand.
But, once terminating during maximum scheduling (such as in the unscheduled time), then wireless device can stop monitoring DL, And provide transmission opportunity to ISM.As replacement, in the unscheduled period, wireless device can the run duration period still Old revival, but do not allow it to expand to run duration the activity time more than the period, and the wireless device can be LTE is that different triggerings perform any process as described above in the unscheduled period.As replacement, wireless device is not adjusted in LTE Spend in the period still can monitor PDCCH according to DRX rules, if however, detecting the east for needing UL to transmit in PDCCH West (such as UL feeds back or UL data), then in the subframe corresponding with the LTE unscheduled periods, wireless device can not be transmitted And ignore PDCCH.If scheduled on PDCCH DL transmission, then, even if exist the risk of the interference from ISM with And the risk of data is unable to properly receive, WTRU can still receive DL data.
In one embodiment, the solution can allow network to be still that WTRU configures short run duration Period, so that optimize saving battery (for example receiving the period 310), but the network still provides enough flexibilities The DL data across the run duration period are dispatched with opportunity.
Fig. 9 shows such a exemplary situation, and wherein scheduling slot is more than the run duration period, but less than DRX is circulated, and the run duration period only occurs in dispatching cycle.
Such a exemplary situation is shown in Figure 10, and wherein scheduled duration and unscheduled duration is all higher than DRX is circulated, and wireless device can not monitor PDCCH in the unscheduled period.
Such a exemplary situation is shown in Figure 11, and wherein scheduled duration and unscheduled duration is more than DRX Circulation, and the run duration period monitoring PDCCH that wireless device can be among the unscheduled period be come across.
In addition, the exemplary situation dispatched and changed with the unscheduled duration inside DRX circulations is shown in Figure 12.In figure In 12, DRX circulations can be less than the cycle of institute's configuration mode, but in another example, the DRX circulations can be bigger.
LTE scheduling slots incorporated herein be defined as LTE can uninterruptedly transmit/receive data when Between.Subframe or TTI can be advanced for or configure in the LTE unscheduled periods, so that another technology is used.In these subframes In, any DL on LTE transmission is all without being correctly received, and any UL transmission can all be disturbed and carried out by another technology Reception (it is assumed that the scheduler of another technology assumes that these subframes are the fact that retain for another technology).Such as Upper described, LTE scheduling/unscheduled pattern can include scheduled duration timer and circulation.When scheduled duration timing When device is currently running, wireless device can follow common DRX processes, and discontinuously monitor PDCCH.When scheduling continues Between timer ends, then wireless device can stop monitoring PDCCH and be transferred to dormancy (such as 312).As replacement, work as scheduling Duration timer is not run, but run duration timer is when being currently running, and wireless device can be monitored PDCCH.Although the processing is described in terms of timer, LTE scheduling/unscheduled pattern can use more explicit Form, in this case can not definition timer.
According to an embodiment, another timer can be defined herein to configure the LTE inactive period, wherein For example, the timer is referred to alternatively as unscheduled duration timer.As replacement, it can not define for LTE not The timer of scheduling, and LTE it is unscheduled be defined as be LTE dispatch timer off-duties period, or for another skill The TTI that art retains.
The value of scheduled duration and unscheduled duration can be by network configurations.As replacement, in ISM and other skills After art is coordinated, wireless device LTE can indicate or advise described value to network.As replacement, wireless device can be work The multiple-of duration and the value that can correspond to more than run duration and be less than DRX circulations.As replacement, LTE is adjusted Degree/corresponding circulation of unscheduled circulation can it is identical with DRX, can be identical with the circulation configured independently of DRX, or can be with DTX circulation multiples are identical.In addition, for determining that the sub-frame offset of LTE scheduling/unscheduled period start time can be with DRX phases Together, the new sub-frame offset that can be pre-defined and/or configure independently of DRX with network is identical.Without situation unrelated DRX Under, embodiment described herein is also applicable.
In one embodiment, by wireless device configuration into when mutual interference avoids pattern in equipment, At this moment scheduling described herein/unscheduled pattern can be used.For example, in a solution, (the example in the unscheduled period Such as when scheduled duration timer off-duty or in the subframe dispatched for ISM), it is possible to not used for DRX work The dynamic time, or if be configured without DRX (is for example possible to inactive or LTE in free time not in wireless device In scheduling) then it is possible that without the activity time.In another solution, it can allow wirelessly to set in the unscheduled period It is standby that activity is in run duration, still, it is allowed to which the additional triggers that wireless device moves to the activity time may not applied to.
In it can keep another illustrated embodiment of scheduled duration timer, wireless device can be following Start under one or more of condition or restart scheduled duration timer.
Network can indicate that the wireless device must start to work in interference avoidance modes in a device to wireless device.Should Handling can be realized by performing new MAC CE (control element) orders, such as so-called ICO MAC CE or RRC signaling.
Wireless device LTE can also detect that it must be with ISM technology co-existences, wherein 1) wireless device LTE can be detected Go out ISM technologies to be activated, and/or 2) ISM technologies can be coordinated with LTE, so that LTE knows that ISM technologies will start soon Work.
Wireless device can be determined:According to circulation and sub-frame offset, the LTE dispatch timers can be activated.
If in addition, timer can be kept, then unscheduled duration timer can be terminated.For example, can be with When starting/restart scheduled duration timer, if unscheduled duration timer is currently running, then this can be stopped Timer.
Wireless device can stop scheduled duration timer under the following conditions.For example, if network to WTRU indicates that it can stop working in interference avoidance modes in a device, then when the wireless device can stop dispatching lasting Between timer.The processing can be realized by performing new MAC CE (control element) orders.
In addition, when wireless device LTE detects that it can stop coexisting with ISM technologies (or other RAT technologies), wirelessly Equipment can stop scheduled duration timer (such as 1) when wireless device LTE can detect that ISM technologies are closed Wait, or 2) when ISM technologies can cooperate with LTE and LTE is known that ISM technologies are stopped).Above-mentioned concept is same Suitable for being supplied to the pattern of wireless device in more explicit form (such as in the form of a bitmap, by different scheduling/unscheduled It is internal that subframe is included in circulation).
In illustrated embodiment, when scheduled duration timer ends or when wireless device can be according to explicit mould When formula enters LTE unscheduled subframes, wireless device MAC can perform one of following or its combination:Stop monitoring PDCCH; As replacement, if run duration timer is not run, only stop monitoring PDCCH;If run duration Timer is currently running, then stops the timer;If DRX inactivity timers are currently running, stop the timer;Such as Fruit DRX retransmission timers are currently running, then stop the timer.
If HARQ RTT timers are currently running, then wireless device MAC can also stop the timer.As for Change, HARQ RTT timers can be continued to run with.If in HARQ RTT timer ends, wireless device determines that it can locate In LTE scheduling slots (or determining that scheduled duration has begun to), then it is fixed that wireless device can select startup DRX to retransmit When device, otherwise will not start DRX retransmission timers.
Wireless device MAC can also stop using one or more DRX to circulate, and/or cancel all pending SR (scheduling Request), and allow high level to know that SR has been cancelled.As replacement, if problem only goes out in DL, then SR can be transmitted, but PDCCH will not be monitored before LTE scheduling slots and/or run duration.
In another embodiment, if random access procedure is carried out, then wireless device MAC can interrupt this Process, and allow high level to know that random access procedure has been interrupted;If accidental access response window is movable, then can be with Interrupt the window;And/or if MAC contentions solve timer and are currently running, then it can stop the timer, and allow high level Know that random access procedure is possible to be interrupted.
In addition, wireless device MAC can also stopped scheduled duration timer to high level instruction, so that high-rise Know that it can not trigger UL transmission;The time of scheduled duration timer is restarted to high-rise instruction;Remove HARQ buffers;Such as Fruit keeps unscheduled duration timer, then starts the timer;Stop sending any HARQ feedback (ACK/NACK);With/ Or stop sending any retransmit.
In one embodiment, when can start scheduled duration timer or when LTE scheduling TTI carrying out When, wireless device begins to use DRX DRX MAC CE orders can be received as it, or can recover last DRX is circulated.Wireless device MAC can indicate that scheduled duration timer is currently running to high level, so that high level knows that it can To trigger UL data transfers.In addition, wireless device MAC can also include sub-frame number, the scheduled duration in these subframes Timer is movable, that is, the sub-frame number before timer ends.
Once scheduled duration can be again started up, then last before stopping DRX retransmission timers can be used Individual value starts the timer.As replacement, in the stopping timer and in LTE scheduling beginning restarting timers Wait, timer can be resetted.As replacement, when LTE scheduled durations have begun to, it is impossible to be again started up DRX re-transmissions fixed When device.
In another embodiment, once scheduled duration is started again at, then stopping inactivity being used to determine When device before last value start the timer.As replacement, in stopping and in LTE scheduled duration beginnings weight When opening the timer, the timer can be resetted.As replacement, when LTE scheduled durations have begun to, it is impossible to open again Move the inactivity timer.
Can also be using other DRX described herein operations, so that RAT can coexist.For example, implement at another In mode, DRX rules and monitoring standard in wireless device can keep not making an amendment.Then, no matter whether other technologies may be used To transmit and (such as no matter have what kind of LTE scheduling/unscheduled pattern), wireless device can revive according to activity time rule Wake up to monitor PDCCH.Even if being not wireless device configuration DRX, the embodiment is also applicable.
In one embodiment, coordinate and ensure that the heavy burden that will not be disturbed and conflict can be transferred to eNB ends.More Specifically, DRX parameters (such as 310) can be provided for wireless device, and LTE scheduling/unscheduled pattern is provided for it. The circulation of these patterns can be consistent with DRX circulations, or as replacing, and new circulation and partially can be provided to wireless device Move, or the new circulation and skew can be the functions of DRX circulations.Pattern described herein is provided to another skill Art, another technology can then transfer to be relayed to the network of their own, to be coordinated.Then, based on the mould Formula, equipment based on the LTE configured unscheduled period (or subframe), circulation and can offset and determine that it can be in which time Perform transmission or receive.In LTE scheduling slots, network can freely dispatch wireless device in UL and DL.
The pattern can be supplied to wireless device, and the eNB by eNB according to any embodiment described herein Wireless device can not be dispatched in the LTE unscheduled periods.But, it may can be disturbed at wireless device end being aware of transmission In the case of, eNB can still dispatch wireless device.This means wireless device still can in the LTE unscheduled periods basis DRX rules monitor PDCCH, or if being configured without DRX, then monitoring PDCCH can also be continued.
If network selection is transmitted in the period, then in order to improve the transmission reliability of the period, eNB can be with Change MCS, RV, power etc..CQI can be based on for how to change transmission choices made.For example, in order to wireless There is the accurate understanding on channel condition, wireless device can report CQI in LTE scheduling slots, so as in nothing in equipment Disturb indicative of channel conditions in period and LTE unscheduled periods.After scheduling/or unscheduled period start, wireless device can One CQI is triggered with every n subframe, or as replacing, periodicity CQI can be triggered.The periodicity CQI can wirelessly set CQI is transported in standby scheduling slot, and acyclic CQI can transport the CQI measured in the unscheduled period.Unscheduled The CQI reported in period can be provided periodically, or only can be provided when eNB is especially asked.
In such scheme, if UL LTE are the directions that possible cause GPS etc technology to go wrong, then can be with Wireless device is allowed only to transmit PUCCH in LTE scheduling slots.If giving PUCCH characteristics, then generation to another The interference of technology may not necessarily be very serious.Thus, network can continuously dispatch DL transmission, and wireless device can not adjusted in LTE Spend and PUCCH feedback is provided in the period, and in LTE scheduling slots, wireless device can continue to provide PUCCH feedback, and net Network can also on PUSCH schedule UL transmissions.Wireless device can not be allowed in the unscheduled period on PUSCH or PUCCH Transmit UL data.More specifically, even if network scheduling DL transmission and accordingly ACK/NACK, which feed back, falls into the unscheduled period, WTRU will not also send PUCCH ACK/NACK.In addition, same situation is also applicable for UL PUSCH transmissions.If Can in the unscheduled period (TTI or subframe) triggering SR, then wireless device can in next available PUCCH resource and SR will not be transmitted before the subframe (such as scheduling slot) of next available permission.Same situation is for RACH transmission It is applicable.In addition, the UE behaviors in the unscheduled period can follow independent or any of the above-described implementation in any combination Mode.
Using the double DRX schemes of dynamic described herein RAT can also be enable to coexist.For example, in an implementation In mode, dynamic double DRX schemes or double scheduling/unscheduled scheme can be used, to allow any of which technology to have enough Opportunity transmit or receive data.More specifically, wireless device may be configured to have two DRX timers or two Individual scheduling/unscheduled timer.Circulation can be identical, but such as run duration (inactivity timer, re-transmission Timer) duration or scheduling/unscheduled between ratio can change.Wireless device can be in each varying cyclically Or change timer.As replacement, two patterns in a complete circulation internal rules.Wireless device can start from offer Run duration and the pattern one of cut-out duration (off duration), may then move into comprising different work With the pattern two of cut-out duration.
In order to avoid shortage is synchronous between wireless device and network, a complete major cycle can determine to start wherein The System Frame Number (SFN) of first mode, wherein the major cycle can be the summation of two circulations.Inside each major cycle It is likely to occur the circulation of two with different timing device by network configuration or both of which.As replacement, wireless device is per N Individual circulation can use second mode to determine the inactivity period of M circulation, be then back to pattern 1.
Can also be using quick mode described herein switching and dynamic coordinate, so that RAT can coexist.For example, so In one group of solution, the method (such as 312) changed for Dynamic trigger and with signal notice mode can be performed.More Specifically, used can be the business model and mode of operation for allowing wireless device to adapt to quick/dynamic change Mode, hereinafter has been described.
As it was earlier mentioned, wireless device may be configured to be used for the permission of the given technology of the device interior with one group Pattern.Or as replace, can define herein one service or use situation pattern finite aggregate, and network and/ Or wireless device then can use the pattern from the set to be operated.
In addition, when another technology can be activated first, or be that wireless device has two kinds of generations dry to network-reporting The technology co-existence disturbed or when detecting the disturbance state in equipment and alternatively including proposed pattern, network can be Wireless device provides a kind of pattern, and (or the pattern of one group of permission is provided as replacement, and optionally provide it currently makes The index of pattern) (for example being received 310).Once receiving configuration, then wireless device can begin to use the pattern, or Person can provide explicit instruction as replacement, network, to be configured to get started using the pattern by WTRU or to wait to be appended Triggering is satisfied (such as 312).If the network configuration pattern, but not yet activate another technology, then this Solution is highly profitable.
In such embodiment, wireless device can be allowed to report the skill for producing interference or being interfered to network dynamic The state of art.More specifically, during one or more conditions below satisfaction, wireless device can be triggered to the finger of network Show:Another technology has been have activated, and the technology is already prepared to transmit or received;Another skill is deactivated Art;Another technology enters park mode or energy saver mode;Another technology exits park mode or energy saver mode;Deactivate Live or terminate current application or service;User has initiated new application or service;Start new higher priority application or Service;Detect the change of use situation;The change of portfolio is detected (for example, if buffer data size exceeds Or less than threshold value, then can trigger report);And/or the report of the instruction disturbance regime as described herein for triggering to network Any condition.
Once triggering is indicated, then wireless device can use L2 signalings to change to network instruction state.MAC can be used CE or RRC information, the wherein message can be noticed one or more in the following with signal:Indicate the shape of another technology State, movable (non-sleep pattern) or deactivates (park mode);Another type of technology;Service or the index of use situation; The index of proposed predefined pattern;And/or the index of buffer status threshold value or classification.It is to be further understood that this report The additional information described in prior embodiments can be included.
Once receiving the instruction, then network can activate or deactivate the use of configured pattern.The activation/ Deactivation command can be performed by L2 or MAC CE signalings, or can be performed by L1 PDCCH signalings or RRC signaling. The message can include to the simple activation/deactivation of the pattern configured, or the rope begun to use is noticed by using signal Draw or explicit mode and alternatively with signal notification time benchmark come change pattern.It is to be further understood that being described herein All solutions in can include time reference so that WTRU and network can be synchronous.The time reference can be with Corresponding to one of the following or its combination:SFN;Sub-frame offset;Length of the cycle in units of frame or subframe;Absolute time Between;Frame index, wherein the pattern starts from the frame that each meets following condition:SFN mod lengths of the cycle=frame index.In addition Sub-frame offset can also be provided.
By using dynamic approach described herein, network need not remove the configuration in wireless device, but it can be moved When state control activates or deactivates the pattern.As replacement, network can notice new pattern and the mould with signal The activationary time or time reference of formula, so as to change the pattern of the Web vector graphic.
In one example, if RAT equipment is WiFi equipment or any equipment for entering park mode, then WTRU This point can be indicated to network, and network can deactivate the use of the pattern, or permission is alternatively provided The pattern that wireless device works in park mode, for beacon reception or the permission station polling data, the data It can then receive and be handled 312 310.When wireless device is revived, wireless device can notify network, and network then may be used To indicate that wireless device begins to use to be described that another technique provides another pattern of more transmission opportunities.
In another embodiment, wireless device can be with the short burst of the free time in dynamic requests LTE, to allow Data are transmitted in another technology.For example, have and be used for if another technology is in park mode and its determination AP The wireless device it is data cached, then wireless device can ask LTE in x TTI without transmission, to ensure that it can be with Order caching data.This can be completed by transmitting instruction to network, and the wherein instruction is used to ask what x no UL were dispatched TTI, or LTE WTRU can not be transmitted in these periods.Once this x TTI terminates, then network can start in UL Middle controlling equipment.Same situation is also applicable for DL.If other equipment determines that it must transmit data, then nothing Line equipment can not dispatch WTRU with signal notice network in x TTI.The quantity of the TTI can be used as one indicated Point and by comprising.The request can be performed by using MAC CE or higher level signaling.Wireless device request uses MAC CE Unscheduled TTI quantity can be dynamic, it can reach a maximum, or can be a fixed number.It is right The request of short-term unscheduled time equally can be make a reservation for or configuration mode set a part, and wireless device can borrow Index is helped to consult these patterns.
In technology of the user to access point or network-side polling message, the transmission mould allowed can be provided for access point Formula, if thus station must be transferred data to as polling result, then access point can be transmitted in the opportunity of permission, So as to reduce the possibility for losing data.Additionally, it will be understood that the pattern and the dynamic control to these patterns are referred to ICO dedicated modes, such as scheduling/unscheduled period/subframe, DRX/DTX patterns, semipermanent scheduling method etc..
In this quick mode handover scheme, once it is determined that trigger certain ISM business, then the ISM in WTRU can be with Immediately begin to transmit ISM business.This can trigger LTE and send request.As replacement, as described in prior embodiments, the instruction It can be sent using active mode (such as before interference is produced).If WTRU has UL licenses, then it can be used This short unscheduled TTI request is advertised to network by the MAC CE in the opportunity of first identification with signal.As replacement, Request to resource can also use the SR in PUCCH to send.
As replacement, if wireless device is without license, then message (such as 308) can not be transmitted to network. But, once the first UL licenses are received, if ISM transmission/reception is still continuing, then wireless device can use the license To send short unscheduled TTI reports to network.
As replacement, in ISM (or other RAT) or even before having started to transmission, the LTE in wireless device can use signal The pattern is advertised to network.Network can permit the request by the response request or offer response to wireless device, Wherein described response indicates the exact amount for the TTI for causing WTRU not to be scheduled due to the result of the triggering.Once wirelessly set Standby to receive response or pattern, then ISM can start its transmission in the subframe of license or according to pattern.
As described herein, it is allowed to by TDM operate for enable illustrated embodiment that RAT coexists can also (individually or Combination) used.Used more particularly for allowing the independent solution that TDM is operated to be combined, to allow equipment to expire Its demand for services under different use situations of foot.In one example, this can be asked by wireless device in report is notified Ask or advise specific LTE scheduling and/or the patterns of the unscheduled subframes of LTE is realized.As it was earlier mentioned, LTE scheduling subframes can be with Refer to dispatch the subframe for using or retaining for LTE, the unscheduled subframes of LTE can refer to the subframe for dispatching other technologies.
The pattern can be using one of following form or its combination:With specified cycle or circulation, circulation and/or subframe The bitmap of skew, wherein the bitmap can include being that a kind of technology (such as LTE) retains or for LTE technologies should made Proposed by specific sub-frame, or occur or without generation disturbance regime subframe (if for example the pattern is advance It is known);Multiple continuous LTE scheduling subframes inside circulation, circulation and/or sub-frame offset (or are not adjusted alternatively Spend subframe);The duration of LTE scheduling subframes inside circulation, circulation and/or sub-frame offset;And/or for wirelessly setting Multiple TTI of the once short unscheduled request of standby request are (for example, if wireless device is just asking network not in multiple companies The wireless device is dispatched in continuous TTI).This can be indicated by single request, or be asked by with above identical To indicate, but cycle values have been configured to infinitary value or some particular value.
In another example, the index of predefined pattern set can be advertised to network with signal, and can also use letter Number notice sub-frame offset.The predefined pattern set can include all possible pattern as described above, for example, at least one Bitmap, wherein containing scheduling/unscheduled pattern inside the bitmap.These patterns can also include at least one bitmap, should Bitmap includes continuous scheduling subframe and continuous unscheduled subframe.The cycle of these patterns can be longer, it is possible thereby to save Space, the pattern can include multiple continuous scheduling subframes inside a circulation.Remaining subframe inside the circulation It is considered as then unscheduled subframe.These patterns can also include at least one entry, and the wherein entry contains wireless device The quantity for the once unscheduled subframe that can be asked for once-through operation.
In response to the pattern asked, wireless device can receive and contain model identical, new pattern or only include The configuration of (such as 1 bit) is indicated, the wherein configuration indicates that it can use asked pattern to WTRU.
Wireless device can start using configured pattern (for example according to bitmap, cycle (or circulation) and timing slip 312).In LTE scheduling subframes, wireless device can be operated according to old LTE processes.In the unscheduled subframes of LTE, Wireless device can perform one of following or its combination.The WTRU can not monitor PDCCH., still can be according to as replacement DRX processes monitor PDCCH.If PDCCH dispatches DL data, then wireless device can not decode PDSCH.As replacement, PDSCH can be still decoded.If ACK/NACK feedback timings are overlapping with unscheduled subframe, then wireless device can not be transmitted PUCCH.If PDCCH dispatches UL data, then if the unscheduled subframe that UL PUSCH transmissions correspondence is configured, then wireless Equipment can not perform UL PUSCH transmissions.
Wireless device can not also perform any UL transmission.For example, if UL retransmits (such as non-self-adapting) correspondence In unscheduled subframe, then WTRU can be held data in HARQ buffers.In each HARQ RTT, retransmission counter It can be incremented by when wireless device can not transmit data because of unscheduled subframe every time.
If SR can be triggered, wireless device can not perform processing, and will not send PUCCH transmission, until tool There is next available scheduling subframe of PUCCH resource.If in addition, SRS can be triggered, then wireless device can wait next Individual triggering, or SRS can be sent in next available scheduling subframe.
If necessary to transmission RACH preambles, then wireless device can be waited according to RACH configuration indexs it is next can With scheduling subframe and the RACH subframes of permission.
If periodicity CSI can be triggered, then wireless device can not transmit CSI.If in addition, wireless device is received Asked to aperiodicity and UL CSI reports time tranfer corresponds to unscheduled subframe, then wireless device can not be transmitted CSI report.
In another embodiment, as shown here, by performing the method for being used for reducing the interference in UL, Ke Yiyun Perhaps RAT coexists.For example, by time-division multiplexing method, LTE and aggrieved technology can coexist together.More specifically, by means of The modes of uplink transmission of UL DTX or reduction in WTRU, can minimize or control the interference to aggrieved technology.
As the part of this method, new UL transmission modes can be introduced into, and wherein the transmission mode is minimized to altogether The interference of technology receiver is deposited, is transmitted while allowing wireless device to carry out it by LTE.It is understood that similar side Method can also be used for other technologies, to avoid disturbing with LTE receivers.
In addition, UL LTE can work in two states, i.e., the conventional UL patterns shown in Figure 13 and reduction UL patterns.Often Rule UL patterns or state (can hereinafter exchange and use) refer to that LTE UL perform routine/old UL and DL LTE and received Journey, such as, but not limited to:Conventional PUCCH transmission, such as periodicity CQI meets the normal stand-by period of DL business The ACK/NACK reports of demand, and normal dispatch request;And the resource according to scheduled in transmission needs and network PUSCH transmission.
When the receiver of symbiont techn can be activity and LTE UL transmission may be interfered to the receiver, Wireless device may be at reducing UL patterns.It is described herein according to multiple triggerings to trigger turning between two kinds of mode of operations Change.Reduction UL mode of operations refer to the pattern that wireless device can not be continuously transmitted.Transmitting carried out modification to UL includes PUSCH and PUCCH transmission modes.It describe hereinafter some processes associated with the mode of operation.And in fig. 13 Show and describe an example of the operation.
The UL transmission modes of reduction can include only performing wirelessly setting for UL transmission in special time or SFN and/or subframe It is standby.The period that WTRU can perform UL burst transfers can determine that wherein network is at each according to the pattern of network configuration All include cycle period and the Burst Period (number for the continuous T TI for for example allowing wireless device to be transmitted in UL in DTX circulations Amount).As replacement, UL transmission modes and time can independently be determined by WTRU.
Pattern described herein can be used for PUSCH transmission or PUCCH transmission.
For PUSCH transmission, wireless device (can be hereinafter referred to as UL DTX moulds according to predefined pattern Formula) or network be supplied to the period of wireless device to transmit uplink shared channel (UL-SCH) or PUSCH.What network was provided This cycle can include one of the following or its combination.The cycle can be made up of DTX parameters, among these including following Ring, Burst Period etc..In Burst Period, wireless device may be configured to have license (such as with the money distributed Source, MCS, TB information etc.), and transmit data thus according to the license.In the SFN provided according to DTX circulations, the license A TTI is suitable only for, or the license goes for multiple subframes inside Burst Period.The license can conduct A part for DTX parameters and be given wireless device, and it can be wireless device can be used in the burst duration period permitted Can.According to BSR or power headroom reporting (PHR) (PHR), if the network determine that to be likely to require more licenses slow to empty for wireless device Storage, then the license can change.But, when wireless device is revived next time, it is possible to return to initial acquiescence License.As replacement, wireless device need not have license.In the wake-up period according to DTX parameters, wireless device can be SR is sent on PUCCH, to ask the correct stock number that WTRU can be allowed to empty buffer in Burst Period.
In one embodiment, network can provide semipermanent license for wireless device, so as in the mode of operation Sustained periods of time in use.When returning to normal mode, wireless device can stop using the semipermanent to permit.If should be permitted Can dynamically change in Burst Period, then wireless device can be returned to when revive next time initial configuration partly forever Long property license.
In addition, wireless device can be in each DTX x subframe circulated or Burst Period revival, during this period, it can To be licensed for transmission according to semipermanent.
Semipermanent license or DRX licenses multiple subframes of intersegmental part can be provided to and wirelessly set when waking up It is standby.More specifically, when wireless device circulates in SFN revivals according to DTX, it can be in many height according to predefined rule The license or the resource distributed are used in frame or some subframes configured.
For above-described two kinds of solutions, semipermanent license and DRX circulations all long enough, thus for For some applications, data can be transmitted in UL while QoS demand is still met.But, wireless device is possible to tool There is a small amount of logic channel for being configured with different demands.Disturbed to minimize and allow to transmit data in time, bilayer can be allowed DRX or semipermanent license.For example, can be the shorter DTX circulations or half of the data configuration of delay-sensitive data or more urgent Permanent license circulation, and can logic channel configuration higher for delay-tolerant degree and being likely to require more bandwidth compared with Long DTX circulations or semipermanent license circulation.As replacement, if this logic channel receives data in its buffer, So wireless device can return to normal transmission mode.
As replacement, if wireless device determines the process for needing to carry out high priority, such as urgent call or delivering State report, then wireless device can independently revive (such as 312) between the DTX periods.Long DTX circulations can postpone The delivering of DLC state reports.In order to reduce the delay associated with reporting delivering, no matter what kind of DTX circulations are, WTRU may be used To perform UL transmission.It is possible to revival to send SR, to receive the license for being used for transmitting the data.
In another embodiment, UL-SCH timing can be by wireless device autonomous control.More specifically, LTE Interacting between victim receiver can allow wireless device to determine to start the Best Times of UL transmission.The determination can foundation Another reception activity of technology (if for example detecting idle period, wireless device can start).The determination can be according to According to the LTE logic channels just transmitted in UL or using allowed maximum delay.The determination can be according to two bullets above (bullet) function.
More specifically, if wireless device can determine that it can transmit data, then wireless device can send SR To indicate that it is desired with transmission to network.If wireless device only has the limited time to transmit the data, then in order to incite somebody to action Interference time minimizes, more it is beneficial that being that the wireless device distributes to more resources by network, thus wireless device Its buffer can be emptied or be transmitted with minimum time quantum.As described above, network can wirelessly be set by means of understanding It is standby to learn this situation in reduction UL patterns.When the SR in the pattern can be received, network can to when Scheduling wireless device takes in.As replacement, wireless device can indicate disturbance regime in SR.More specifically, SR can It is modified to comprising notifying or bit, when wireless device determines receiver on another symbiont techn by from UL's During interference, the notice or bit will be set.This needs to modify to the form of dispatch request, or interpretation ratio again It is special.
In DTX cyclic processes or in reduction UL patterns, wireless device can ignore received UL licenses.As for Change, if detecting the change of semipermanent license in PDCCH, then WTRU can change License Value, and only call out The awake time uses.
For PUCCH transmission, the transmission of LTE up-links can also include PUCCH, among these including for DL business ACK/NACK feedbacks, channel quality indicate (CQI) and dispatch request.In order to keep minimum to the interference of symbiont techn, The PUCCH mode of operations of reduction can also be included by reducing UL states.Although the PUCCH of reduction can strengthen performance, wirelessly Equipment can continue normal PUCCH transmission, while reducing the time of UL transmission.
In order to allow the PUCCH transmission of reduction, HARQ ACK/ will not be provided when WTRU is in reduction UL patterns NACK feeds back.During this period, e nodes B can perform autonomous HARQ and retransmit, and WTRU can then decode DL data, and will not Send any HARQ ACK/NACK.
The need for further reducing transmission PUCCH, the quantity of CQI can be limited.More specifically, The CQI cycle can make the cycle of UL DTX patterns or the cycle of semipermanent license into.It is used as the one of DTX patterns Part, if burst transfer continues a small amount of TTI, then wireless device can more frequently send CQI.
Finally, dispatch request can be constrained to be triggered according to one of DTX patterns.But, touched if meeting some Hair, and need to transmit SR as described above, then WTRU can still transmit PUCCH.
As replacement, once SR can be triggered, then wireless device can terminate that (such as WTRU can be kept with waiting timer SR maximum time) and waking up period wait.
In addition, in another embodiment, still PUCCH can be transmitted according to normal mode triggering.But, in order to The potential interference that he is likely to result in is reduced, only PUCCH can be transmitted in a frequency.It is currently possible to provided according to network Index transmits PUCCH using frequency hopping processing.
PUCCH can be narrow band signal (1RB), be transmitted on the edge of its main on both frequencies UL bandwidth.Therefore, In order to reduce interference, if these frequencies are corresponding to one of frequency caused interference with, WTRU will not perform frequency hopping to the frequency Processing.Then, PUCCH second time slot can be transmitted on next opportunity on the noiseless edge of identical.This can be with Realized by one of the following or its combination.Network can give the distribution of WTRU only ones frequency, and it is distributed in the frequency Upper transmission PUCCH.
In addition, wireless device can be to perform frequency hopping processing in spontaneous two frequencies for stopping at network instruction, and only exist Do not result in and be transmitted in the frequency of interference.Once transferring state, then network, which is known that, there occurs this implicit behavior. As replacement, network can be two noiseless frequencies of wireless device configuration, for transmitting PUCCH.
In an illustrated embodiment, wireless device can be allowed to send its PUCCH in single noiseless region.But It is to conflict or disturb in order to avoid being produced with other wireless devices using same asset, network can be these wireless devices Use code division multiplexing.The information that wireless device needs can be provided by network explicit.SRS transmission can also be in identical arrowband area Transmitted in domain.
If wireless device detects its unscheduled period for being in DTX patterns, wireless device can be independently to network SRS is transmitted, and waits scheduling slot, to recover its periodic SRS reports processing.As replacement, this can be by network Configuration, that is to say, that network can indicate whether to allow it not report SRS in the unscheduled period to wireless device.As for Change, compared with being reported in scheduling slot, wireless device can independently or network can be reduced unscheduled by configuring The cycle of SRS reports in period.This is very beneficial in the case of the unscheduled period is very long.
In order to determine when to be changed between two kinds of mode of operations, wireless device can use one in following method Individual or multiple conversions to trigger between this quasi-mode.Although however, it should be understood that trigger criteria is in reduction UL DTX patterns Context described in, but these standards can be used for similar DL mode of operations, such as DRX.
For example, although wireless device can work in conventional UL patterns, but enabling victim receiver or opening Dynamic DL is received and wireless device can determine UL LTE or when potentially interfering with the receiver of another technology, WTRU One of following or its combination can be performed.Wireless device can independently be moved to reduction UL states.It is being moved to reduction UL After state, wireless device can be by the transformation informing network of UL mode of operations.As replacement, wireless device will not explicit notification Network, but network independently can determine wireless device operations in reduction UL patterns based on wireless device behavior.As for Change, wireless device only can just transform to reduction UL states in the case where obtaining coming the explicit configuration of automatic network.More specifically, Wireless device can use above-described any process or to be possible to enable victim receiver to network signals. Then, network explicitly can be moved to reduction UL states with signal notice wireless device, and can also provide new configuration Parameter.
Once in UL patterns are reduced, then wireless device can return to routine according to one of following triggering or its combination Pattern.The wireless device can be back-transformed when network explicit is indicated.As an alternative or supplement, wireless device can be It is back-transformed when disabling victim receiver or technology or the receiver or technology inactive in some period.If This condition is met, then wireless device can start normal mode transmission, then send and notify to network.As replacement, wirelessly Equipment can send the notice of equipment no longer activity according to said process to network, and wait explicit instruction.
As an alternative or supplement, wireless device can be done being able to carry out the receiver generation no longer to another technology It is back-transformed when switching between the frequency or RAT frequency disturbed or between RAT.The wireless device can also initiate high preferential It is back-transformed when level service, logic channel or high priority access grade service (such as urgent call).
Before reduction UL pattern transmission is started, the satisfiable additional conditions of wireless device can be included in LTE technologies Hold ongoing activity.The priority of the logic channel of QoS more specifically comprising data or these services.Citing comes Say, if delay-sensitive application is movable, then WTRU may remain in conventional UL patterns.Wireless device can also be by this Individual information is supplied to network (cache size of such as logic channel), and thus network can rightly dispatch DTX patterns.Additional strip Part can also include the relative priority of the application between LTE and another technology.For example, if it is considered to LTE application tools There is higher priority, then LTE may remain in conventional UL patterns, otherwise it can transform to reduction UL patterns.
The pattern described in these sections is provided to another technology, so as to coordinating transmissions and the time received. Another technology can also provide this information to its network, and thus another network (such as transmitting node) is known that It can not perform the time of transmission.
Back-off described herein or scalable scheme can be also used for allowing the RAT in wireless device to coexist.For example, making For the replacement of time domain solution, wherein coordinating the transmission between RAT to ensure or minimize simultaneous transmission, the biography It is defeated to be reduced into carrying out on one or more RAT, to reduce interference level, the biography without preventing any instant completely It is defeated.
One such method can will be can apply to still by wireless device to replacing the noisy some frequencies of RAT The quantity of power of section is close to known threshold.When realizing transmission in public or overlapped frequency bands, wireless device can be determined can be every The quantity of power applied on one RAT, each RAT minimizes or eliminated the transmission fault replaced on RAT.For this purpose, Wireless device can combine in ICO functions, the Transmission Time Interval that the function is transmitted at the same time and distribute work(between rats Rate.
When detecting to the interference for replacing RAT beyond threshold value, wireless device can apply back-off and scale progress In transmission transimission power, thus interference is maintained at below threshold value.It should be noted that power scaling may cause HARQ Retransmission number and the growth for remaining HATQ error rates.
In one embodiment, wireless device power scaling may cause bust this.In this connection, UL is permitted to adjust Section to the available WTRU transimission powers reduced are very important.In order to reduce the size of UL licenses, UE can give birth to scheduler Into explicit signal, for identifying back-off or scaling condition, and it is possible to identify the power reduction grade on specific band.
A kind of method that can be used to identify power scaling event in LTE is to use existing MAC CE power headroom reports Accuse (PHR).In LTE R10, due to the back-off caused by MPR or P-MPR in PHR be identified (also It is to say, the leading Pcmax, c calculating of (dominate) of its factor).Added field or code-point in MAC PHR CE can be referred to Fixed, it is indicated because of back-off or scaling caused by the interference in equipment.In LTE versions 10 (R10), for each For the SCell of activation, PHR includes power headroom (PH) and license (Pcamx, spy c) needed due to other cells Due to the power reduction of implementation.For each wave band or component carrier, minimize to required for other RAT interference The specified quantitative of back-off or scaling can be added in the PH and Pcmax, c noticed with signal as additional parameter, Huo Zheke To be used as additional factor in calculating Pcmax, c in the SCell activated for each.
In addition, use can also be added to the secondary power rollback or amount of zoom required for other RAT interference by minimizing In other back-offs or scale factor of frequency range or component carrier.If can be noticed with signal actual rollback or scale because Number, then wireless device, which can identify or not identify these, causes the source of power scaling.Identifying the particular source can be beneficial to Potential back-off or scaling in scheduler prediction subsequent transmission time interval.Therefore, if in existing rollback or contracting Put in factor added with additional back-off, then indicate it is still to have very much the reason for comprising back-off for being reported .
In LTE versions 10 (R10), wireless device can be allowed to reduce its maximum as the function of the signal transmitted Power output, is limited with avoiding radiating beyond wave band.Based on implementation, wireless device can use complete permission power reduction or It is less value.In each subframe i, for given component carrier (CC), wireless device can be based on LTE configurations Its power reduction needed is determined with license.The processing is referred to alternatively as MPRactual,c(i) it is maximum allowable, and in the subframe Power output is:
PCMAX,c(i)=MIN { PEMAX,c,PPowerClass-MPRactual,c(i)-ΔTC,cEquation (1)
Wherein
PEMAX,cIt can be the peak power (being used for CC) that higher is noticed with signal.
PPowerClassCan be the maximum WTRU power outputs for the WTRU grades.
MPRactual,cCan cause because of peak power reduction (MPR)/additional MPR (A-MPR) effects and by WTRU The actual power taken reduces and (is used for CC).
ΔTC,cIt can be the constant power skew (being used for CC) of the function of transmission bandwidth (BW).
In addition, in LTE versions 10 (R10), wireless device can be allowed to reduce its peak power output, for use in Power management caused by the unknown power demand of LTE schedulers.In each subframe i, for given component carrier (CC) for, wireless device can configure according to LTE and permit to determine its power reduction needed.The processing is referred to alternatively as P- MPRactual,c(i) the maximum allowable power output, and in the subframe is:
PCMAX,c(i)=MIN { PEMAX,c,PPowerClass-MAX(MPRactual,c(i),P-MPRactual,c(i))-ΔTC,c(i) } (equation 2)
A kind of possibility is:Back-off caused by minimizing the interference to other RAT can be one attached Plus item, such as RATbackoff, c (i), and maximum allowable power output are:
PCMAX,c(i)=MIN { PEMAX,c,PPowerClass-MPRactual,c(i)–P-MPRactual,c,-RATbackoff,c(i)-Δ TC,c(equation 3)
But it is more likely that back-off is possible to minimize interference to other RAT, and MPR will not be supplemented Reduce, on the contrary, it is to reduce parallel, thus can essentially using that the effect in this 3 kinds of reductions processing is larger one with MPR It is individual.In this case, peak power output is:
PCMAX,c(i)=MIN { PEMAX,c,PPowerClass-MAX(MPRactual,c,P-MPRactual,c,RATbackoff,c(i))-Δ TC,c(equation 4)
In order to provide timely PHR information to eNB schedulers, different report triggerings are can specify that.Due to being difficult advance Other RAT of predicted impact interference, it is therefore necessary to which specific triggering is provided, with when detecting the interference for influenceing other RAT It is quick that PHR is provided.Similar with the P-MPR triggerings in R10, a kind of method for being used to realize the processing can be in specific SCell RATbackoff, c (i) change exceed configured threshold value when triggers PHR.In other factors, what is configured returns Moving back threshold value can depend on specific to deployment scenario and the eNB scheduler designs implemented.
For MAX (MPR can be passed throughactual,c,P-MPRactual,c(i),RATbackoff,c(i)) determine in power reduction Other factors for, if the back-off applied or to other RAT interference can with other factors parallel computation, Then it is possible that there is such situation, even if wherein because RAT disturb caused by rollback and the threshold crossings that are configured, but If it is leading by MPR/A-MPR effects or P-MPR effects, then it is that will not produce shadow for actual power rollback Loud.Therefore, in order to minimize unnecessary report, because RAT retracts, PHR triggerings can be confined at this caused by change Factor controls the rollback (Pcmax, when calculating c) carried out applied for cell.
It is similar to the power management in LTE R10 according to an illustrated embodiment, because being disturbed in equipment in WTRU It can be answered with the back-off or scaling caused by other reasonses in time-domain window rather than based on Transmission Time Interval With.The reason done so is that UL license scheduling is not necessarily to adjust immediately.By in some period rather than to be specific Back-off or scaling are applied in transmission, can be improved the UL matched with back-off or zoom level and be permitted.In addition, to power Retract or the mark of scaling event can also submit to forbid timer, timer-delay MAC CE PHR.In such case Under, the application of back-off or scaling can postpone until eNB schedulers can transmit or realize MAC CE PHR.Removing Similar method can be used when back-off or scaling.In this case, only when scheduler is reported or is realized When the rollback or scaling of reduction, back-off or scaling just can actual reductions.This solution has appropriate support LTE UL The benefit of the power management of license, and when transmission on other RAT are quickly reactivated, this solution is minimized Interference to other RAT.
Power reduction value and reason can also report that, to network, the wherein message can be detected in UE by notification message Triggered when disturbance regime in equipment, and power management process as described above can be performed.
Additional prevention mechanism is can also carry out in idle mode, such as in response to receiving and handling with wireless device The information for being associated with this mechanism of (such as in 310 and 312).
If wireless device may be at not having pending data in idle condition, and the buffer of wireless device, then Wireless device can limit or coordinate ISM equipment (or supporting RAT another component), to protect the actual behaviour of wireless device Make, so that data will not be transmitted in paging and measurement period.For example, this be able to can be activated (for example in symbiont techn ISM or GPS can be activated) and wireless device be performed when be ready for connection to LTE system.
If wireless device can be idle, then the time of change to another frequency is unimportant.Wireless device It may remain in idle pulley, while RAT technologies can be activated, such as ISM technologies.But, it is used as this solution A part, wireless device can notify network to have activated RAT, such as ISM technologies.This can allow wireless device in advance from Open the frequency.In order to notify network in idle mode, wireless device can use RRC connection request message.RRC connection request 1 bit in message indicates to can be used for indicating to ask activation or symbiont techn (its being activated in device interior to network It is possible to produce in equipment and disturbs).As replacement, it can be introduced into RRC connection request and new set up clause (such as in equipment Technical activity), network can respond wireless device by the RRC refuse informations redirected with reason.
As replacement, once having initiated RRC connections sets up process, then wireless device can to network signals ISM equipment it The RAT components or equipment of class are movable.The notice can be set up in completion in RRC connection request or RRC connections to be present.So Afterwards, network can select wireless device being sent to connection mode (such as by 310 message received), and perform as above One of described operation (such as by the processing 312), or alternatively to wireless device give redirection information.
Wireless device can provide the temporary mode together with the instruction with information as described above or report to network, Wireless device just can allow appropriately to receive RRC connections using the temporary mode sets up message.Together with the pattern, nothing Line equipment can specify that benchmark timing, and thus network is known that ISM equipment without transmitting and it is possible thereby to being used for by eNB The downlink subframe of downlink transmission.The pattern that wireless device is used and noticed with signal can be explicit mode.Make To replace, wireless device and network be pre-defined and known default mode can be used for receiving RRC connections and set up message.Work as net When network receives the instruction in RRC connection request, it can use this default mode to determine subframe, wherein in the burst RRC connections are dispatched in DL to set up or RACH msg4.
As replacement, WTRU can provide the index of predefined pattern set, and WTRU can just use the pattern temporarily, directly To the new pattern of network request or operation.At wireless device end, wireless device can use noticed pattern to determine that it can With the subframe monitored in DL.For example, when macContentionResolution timers are run, wireless device can be supervised The subframe that will not be transmitted depending on other equipment or the LTE scheduling slots according to the pattern.As replacement, wireless device can be with Continuous reception is performed, and message is transmitted in correct subframe by network.If network do not support this feature and It can essentially transmit response in any subframe, then this processing would is that what is be highly profitable.
